I was at a book store the other day and ran across a book on Chevrolet police cars over the years. They have a picture of a 69 Chevelle 4 door hardtop with the RPO police package. It also said that they had 325 horsepower 396 engines in them. It was the only body style available with the police option. If this is the case there must be some original 396 four door cars out there. Does anybody have anymore info on these cars?
